Tiny microheaters that can prompt chemical changes in surrounding material may provide the means to more easily grow replacement tissue for injured patients and form the basis for medical sensors that could quickly detect pathogens, according to researchers at the University of Washington who are the first to demonstrate the process.
The key to the technique, according to Associate Professor Karl Böhringer in the UWs Department of Electrical Engineering, lies in temperature-driven changes in the material with which the less-than-one-millimeter-wide electric heaters are coated. Proteins stick to the material as its temperature rises, and release when it goes back down. That, according to Böhringer, opens the door to a wide array of possibilities.
"The proteins stick locally to the areas we heat, and we can stick cells to the proteins," he said. "This provides a relatively simple, low cost way of creating cell chips to run experiments and to create other useful devices."

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
